John H Warden: FAQ
- Where is John H Warden?
- In Baraga County, Michigan (MI). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.
- How big is John H Warden?

- Who owns John H Warden?
- EIA-860M names L'Anse Warden Electric Company LLC as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.
- Is this the same as John H Warden LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — L'Anse Warden Electric Company LLC here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "John H Warden LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
- Is John H Warden still running?
